60+50.45x-57.95x=0
Tangohia te 57.95x mai i ngā taha e rua.
60-7.5x=0
Pahekotia te 50.45x me -57.95x, ka -7.5x.
-7.5x=-60
Tangohia te 60 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-60}{-7.5}
Whakawehea ngā taha e rua ki te -7.5.
x=\frac{-600}{-75}
Whakarohaina te \frac{-60}{-7.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=8
Whakawehea te -600 ki te -75, kia riro ko 8.
